I certainly don't disagree. However, IF there's a failure of any kind.....a rusted line lets loose, a wheel cylinder blows out, a bursted brake hose and all you will have is MAYBE one pump on the brake pedal to slow it down "a little" and if you have no parking brake, then you got "NUTHIN" after that one last pump. Yup, they work great for sixty plus years, but there's always that ONE time.
